  Nuclear factor 90 negatively regulates influenza virus replication by interacting with viral nucleoprotein.
 PMID: 19494010       2009       Journal of virology
Abstract: This interaction was prevented by a mutation, F412A, in the C-terminal region of the NP, indicating that the C-terminal of NP is required for NF90 binding.


  Co-circulation of two genetically distinct sub-groups of A/H3N2 influenza strains during the 2006-2007 epidemic season in Corsica Island, France.
 PMID: 19502107       2009       Journal of clinical virology
Abstract: One of these sub-groups was distinguished by the substitution H156Q whereas the second demonstrated at least one of the 3 other additional mutations (R142G, L157S and K173E) common to the HA1 sequence of A/Nepal/921/2006 reference strain.


  Novel genotypes of H9N2 influenza A viruses isolated from poultry in Pakistan containing NS genes similar to highly pathogenic H7N3 and H5N1 viruses.
 PMID: 19517011       2009       PloS one
Abstract: The hemagglutinin (HA) sequences of all isolates were closely related to H9N2 viruses isolated from Iran between 2004 and 2007 and contained leucine instead of glutamine at position 226 in the receptor binding pocket, a recognised marker for the recognition of sialic acids linked alpha2-6 to galactose.
Result: At residue 15, all the H9N2 UDL viruses encode isoleucine and the amino acid substitution of V15I is common within H9N2 lineages.
Result: In addition, a substitution from tryptophan to arginine at position 403 was observed in 11 of the 12 viruses recently isolated from Pakistan; this substitution was present in Qa/HK/G1/97 but not in other H9N2 viruses, including those from the UAE from 2000 to 2003 and, importantly, not in the human (e.g.
Result: It is striking that


  Amantadine-resistant influenza A (H3N2) viruses in Iran.
 PMID: 19537916       2009       Acta virologica
Abstract: In investigating the frequency of amantadine-resistant IAVs (H3N2) circulating in Iran in 2005-2008, we found that M2 sequences of recently circulating viruses that were amantadine-resistant contained a Ser31Asn mutation.


  Palmitoylation of the influenza A virus M2 protein is not required for virus replication in vitro but contributes to virus virulence.
 PMID: 19553312       2009       Journal of virology
Abstract: Recombinant viruses encoding M2 proteins with a serine substituted for the cysteine at position 50 were generated in the A/WSN/33 (H1N1) and A/Udorn/72 (H3N2) genetic backgrounds.


  Mutations in influenza virus replication and transcription: detection of amino acid substitutions in hemagglutinin of an avian influenza virus (H1N1).
 PMID: 19553505       2009       FASEB journal
Abstract: The comparison of the sequences obtained from analysis of viral genome and peptide found seven variations between HA gene and protein, namely E103K, R130K, T169I, I338V, N387S, S398I/L, and I399S in HA.


  Dynamics of antiviral-resistant influenza viruses in the Netherlands, 2005-2008.
 PMID: 19591877       2009       Antiviral research
Abstract: For adamantanes, a high proportion (>74%) of A(H3N2) viruses had the S31N mutation in M2 protein, while variation in the HA(1) region of adamantane-sensitive viruses suggested that adamantane-sensitive variants were reseeded into the Dutch population and re-emerged as drug-sensitive due to M-segment reassortment.


  Molecular and phylogenetic analysis and vaccine strain match of human influenza A(H3N2) viruses isolated in Northern Greece between 2004 and 2008.
 PMID: 19615420       2009       Virus research
Abstract: Receptor binding sites were conserved in 2004-2005 and 2005-2006 strains whereas a variation was observed in all 2006-2007 strains (H195Y).


  Elastase-dependent live attenuated swine influenza A viruses are immunogenic and confer protection against swine influenza A virus infection in pigs.
 PMID: 19625412       2009       Journal of virology
Abstract: Based on the immunogenicity results, the R345V virus was further tested in a protection trial in which pigs were vaccinated twice with R345V and then challenged with homologous A/Sw/Saskatchewan/18789/02, H1N1 antigenic variant A/Sw/Indiana/1726/88 or heterologous subtypic H3N2 A/Sw/Texas/4199-2/9/98.
Abstract: Our data showed that two vaccinations with R345V provided pigs with complete protection from homologous H1N1 SIV infection and partial protection from heterologous subtypic H3N2 SIV infection.
Abstract: Previously, we generated two elastase-dependent mutant SIVs derived from A/Sw/Saskatchewan/18789/02(H1N1): A/Sw/Sk-R345V (R345V) and A/Sw/Sk-R345A (R345A).
Abstract: We report that intratracheally administrated


  Surveillance and oseltamivir resistance of human influenza a virus in Turkey during the 2007-2008 season.
 PMID: 19626608       2009       Journal of medical virology
Abstract: H275Y (H274Y according to N2 numbering) mutation, which is known to confer resistance to oseltamivir, was detected in 6 out of 30 (20%) H1N1 isolates from four cities (Istanbul, Bursa, Ankara, and Izmir).
Abstract: The D354G mutation was observed in all oseltamivir resistant H1N1 isolates but not in the oseltamivir sensitive isolates.
